Problems solved by technology

The disadvantages of this method are: there will be toxic and harmful gases in the pipeline, which will pose a great hidden danger to the life safety of workers; even if the content of toxic gases in the pipeline is low, it will also bring harm to the health of workers; manual cleaning of sludge Will increase a lot of labor costs
[0004] (2) Robot dredging: For robot dredging, on the one hand, there are no mature robots in China that can be used for large-scale pipeline dredging, and most dredging robots are still in the research and development stage; on the other hand, the diameter of the working well There are great restrictions on the size of the robot: if the robot is too small, the crawling power will be small, and it will not be able to crawl stably during the sludge pumping process; if the robot is too large, the robot will not be able to enter most of the working wells, and larger work needs to be excavated Well, meet the construction conditions

Embodiment Construction

[0042] In this embodiment, a double-roller unilateral movable large-scale chain combines figure 1 and figure 2 , comprising a chain mechanism 73 and a traveling mechanism 74, the chain mechanism 73 comprising an outer chain plate 731, an inner chain plate 732, the outer chain plate 731 being mounted on the outside of the inner chain plate 732 through a shaft pin 734; the traveling mechanism 74 comprising a roller 741 and a support Plate 743, support plate 743 is fixed on inner chain plate 732 bottoms, and roller 741 is movably installed on support plate 743 bottoms, and can do rolling motion at support plate 743 bottoms.

[0043] The above scheme is a single-plate structure, and it can also be set as a double-plate structure during operation, that is: combined figure 2 , there are two inner chain plates 732, and the shaft pin 734 is located between the two inner chain plates 732; two outer chain plates 731 are provided, and the two outer chain plates 731 are respectively in...

Abstract

The application provides a double-roller unilateral movable large-scale chain and its application, belonging to the technical field of conveying or separating dredged or excavated materials in water conservancy projects. It includes a chain mechanism and a travel mechanism installed under the chain mechanism. The chain mechanism includes an outer chain plate, an inner chain plate, roller shaft pins and bushings, and the travel mechanism includes rollers, wheel pins and support plates. The inner chain plate is connected to the support plate. , to realize the connection between the chain mechanism and the traveling mechanism. The application of this application to pipeline dredging has the advantages of small factors affected by the size of the site, high efficiency, and stable work.

Description

technical field [0001] The application relates to a double-roller unilateral movable large-scale chain and its application in pipeline dredging, belonging to the technical field of conveying or separating dredged or excavated materials in water conservancy projects. Background technique [0002] In the process of pipeline desilting, there will be situations where the working well is too small, which makes the operation difficult and the equipment cannot enter the underground pipeline. The existing operation methods are mainly divided into two types: manual dredging and robot dredging: [0003] (1) Manual dredging: After the pipeline is blocked, the sewage in the pipeline is drained, and then the sewage is manually descended into the pipeline for dredging. The disadvantages of this method are: there will be toxic and harmful gases in the pipeline, which will pose a great hidden danger to the life safety of workers; even if the content of toxic gases in the pipeline is low, i...
